Factors associated with burnout among hospital-based healthcare workers during the COVID-19 pandemic: A cross-sectional CRACoV-HHS study

To assess the prevalence of burnout and associated factors among healthcare workers (HCWs) working in a hospital admitting patients with COVID-19. Burnout among HCWs is related to age, gender and occupation. However, little is known about organisational factors associated with burnout during the COVID-19 pandemic. A cross-sectional study of 1412 hospital HCWs (748 nurses) was carried out via online survey during the COVID-19 pandemic between 4 and 19 January 2021. The Maslach Burnout Inventory-Human Services Survey, the Checklist Individual Strength questionnaire, the interRAI items covering mental health, the WHO questionnaire items assessing HCWs' preparedness and exposure to SARS-CoV-2 were used. Univariable and multivariable linear regression analyses were conducted to clarify factors associated with emotional exhaustion (EE), depersonalisation (DP) and personal accomplishment (PA). This study adheres to the STROBE guidelines. Burnout prevalence varied from 10.0% to 22.0%. Most respondents (83.6%) reported low PA, 22.9% high EE and 18.7% high DP. Nurses and physicians had the highest levels of EE and DP. Staff exposed or uncertain if exposed to contaminated patients' body fluids and materials had higher levels of burnout. Preparedness (training) (b = 1.15; 95%CI 0.26 to 2.05) and adherence to infection prevention and control procedures (b = 1.57; 95%CI 0.67 to 2.47) were associated with higher PA, and accessibility of personal protective equipment (PPE) (b = -1.37; 95%CI -2.17 to -0.47) was related to lower EE. HCWs working in wards for patients with COVID-19 reported lower EE (b = -1.39; 95%CI -2.45 to -0.32). HCWs who contracted COVID-19 reported lower DP (b = -0.71, 95%CI -1.30 to -0.12). Organisational factors such as better access to PPE, training, and adherence to infection prevention and control procedures were associated with a lower level of burnout. Healthcare managers should promote strategies to reduce burnout among HCWs with regard to preparedness of all staff.
